dad882a12e weston-log: Rename scope's 'begin_cb' callback to 'new_subscriber'
Rather than using 'begin_cb' rename it to a more suitable name.

Further more instead of using the scope use the subscription to pass as
an argument. The source scope is attached to the subscription when
creating it so we can access it that way.

This also adds a _complete and a _printf method for the subscription
such that the callbacks can use to write data to only _that_
subscription and to close/complete it, otherwise writing to a scope
results in writing to all subscriptions for that scope which is not
correct.

In the same time, the scope counter-parts of _write and _complete will
now use the subscription function as well.

9f71a4ad85 weston-log: Introduce subscribe functionality
As described in e10c9f89826bb: "weston-debug: Introduce...", the
subscriber object need further functionality to make use of it.

Current form of the weston-debug protocol would not need this, as it
creates underneath a new subscriber each time a client connects and
subscriptions are created/destroyed automatically with the help of
wayland protocol. For other types of streams, we require to manually
create a subscriber and to subscribe to log scopes.

This patch introduces the ability to create subscriptions, and
implicitly to subscribe to (previously created) scopes.

In the event the scope(s) are not created we temporary store the
subscription as a pending one: a subscription for which a scope doesn't
exist at the time of the subscription. When the scope for which the
subscription has been created we take care to create the subscription as
well.

While at it the documentation bits are modified accommodate the subscribe
method and its further functionality.

Lastly, it removes an unlikely case when a scope is not created so we
avoid any kind of dandling (pending) subscription in case there is
subscription to it. We can only do something about in the destroy part
of the scope.
